Specification of Letters Patent.

Patented Feb. 20, 1906.

Application filed Jul;T 6, 1905. Serial No. 268,377.

To all whom it may concern:

Be it known that I, WILSON E. SYMoNs, a citizen of the United States,residing at Pittsburg, in the county of Crawford and State of Kansas,have invented a new and useful Locomotive-Truck, of which the followingis a specification. j This invention relates more particularly toimprovements in four-wheeled leading-trucks of locomotives, though thereare certain features of novelty not necessarily limited theretoi; aswill be apparent to those skilled in the ar )ne of the principal objectsis to provide a main frame cast in one piece, thereby greatly reducingthe number of parts to be fitted, and consequently reducing the cost ofmanufacture and maintenance, while increasing the strength anddurability of the truck.

Another object is to provide a structure of the above character thatwill permit the application of the wheels and axles without thenecessity of jacking up the truck from the rails a distance equal to thelength of the jaws or pedestals.

A still further object is to improve the various details of constructionin order to secure simplicity.

One embodiment of the invention is illustrated in the accompanyingdrawings and is described' in the following specification. An inspectionof the claims hereto appended will show thatthe invention is not limitedsolely to this embodiment.

' In the drawings, Figure 1 is a plan view of the truck. Fig. 2 is aside elevation of the same, the wheels on the nearer side being removed.Fig. 3 is an end elevation of the truck. Fig. 4 is a longitudinalsectional view the main frame, together with the separate pedestals andboxing-shoes detached. Fig. i 6 isa cross-sectional view through themain frame and equalizer-bars. Fig. 7 is a secj tional view onthe line 77" of Fig. 6. Fig. 8 is a detail sectional view on the line 8 8 of Fig.5. Fig. 9 is a top plan view of one of the l binders for connecting theassociated pedestals. Fig. 10 is a side elevation of the same.

In the embodiment illustrated a main frame is employed that is of asingle piece and of cast-steel. This main frame consists i of side beams11, end bars 12, connecting the ends of said side beams and integraltherewith, and an intermediate transom 13, connecting the centralportions of the side beams and formed integral with the same. Each sidebeam, as particularly lshown in Fig. 8, consists of an upright web 14,provided with inset upper and lower flanges 15 and 16, formedupon theupper and lower margins of the web. The flanges 15 and 16 terminate atthe ends .of the side beams and the end bars 12 are invertedsubstantially L-shaped in cross-section, consisting ofangularly-disposed flanges 17 and 18, the former of which constituteupright webs, and the flanges 18 projecting outwardly.

The transom 13 consists of a central bearing or femalecasting having atubular bowlshaped body 19 with a circular top or bearing-plate 20,carrying an upstanding peripheral flange 21, and having a centralbolt-receiving opening 22. On opposite sides of this bearing extend webs23, integrally joined to the bowl-shaped' body and to the upright webs14 of the side beams, as illustrated in Fig. 6. Lower flanges 24,extending on opposite sides of the webs 23 and located longitudinallyalong their lower margins, are integrally connected to the lower anges16 of the side beams, while upper oppositely-projecting flanges 25,located along the upper edges of the webs 23, extend from the annularflange 21 to the upper flanges 15 of the side beams, these flanges 25tapering in opposite directions, as shown in Fig. 1.

Depending from the end portions of the side beams are integral pedestalsconsisting of bearing-plates 26 and brace-webs 27. The outer sides ofthe plates 26 are provided contiguous to their upper ends with recesses28. Cooperating with these integral pedestals are other pedestals 29,consisting of bearingplates 3() and bracing-webs 31, said pedestals alsohaving tops 32, that bear against the under sides of the side beams 11outside the integral pedestals and being secured thereto by bolts 33,which pass through said tops 32 and through the lower. flanges 16 of theside beams. The inner sides of the pedestals 29 are provided with seats34 similar to the seats 28 of the integral pedestals. These seats areadapted to receive similar-shaped lugs 35, formed upon the upper ends ofshoes 36, that detachably fit against the inner faces of the pedestalsand are held in place by binders 37, bolted, as shown at 38, to the IOOIOS

IIO

boxes 40. Each of the equalizing-bars consists of an upright web 46,having offset upper and lower marginal flanges 47. A air of theequalizing-bars are associated wit side beam 1 1 of the main frame,being located on opposite sides of the same, as illustrated in Fig. 1,the bars tapering toward their ends, as

, shown. Hanger-stirrups 48 are pivoted by work when the ot means ofbolts or pins 49 to and between the equahzer-bars of each set, andsupported by .the hanger-stirrups are springs 50, which springs bearagainst the under sides of the side beams 11 at the juncture of thetransom 13 therewith.'

The truck above described is very strong and durable and yet is com osedof very few parts, the main frame, inc uding certain of the edestals,being of one piece which can be rea ily cast and rerluires but littlemachineer parts are assembled therewith. At the same time by having theouter pedestals detachable the 4axles and wheels can be readily appliedwithout the necessity of jacking the entire truck-body from the rail adistance equal to the height of the pedestals. The various parts are,furthermore, simple in structure, yet very strong to withstand thenecessary jars and strains. At the samen time these parts are light inweight and can be readily manufactured.

` From the foregoing it is thought that the construction, operation, andman advantages of the herein-described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.
